Two great flights! The second flight had lots of wind to fight against, hence the wiggle near the end. The nose cone was 3D printed, and the stress of chute ejection broke the plastic connecting it to the shock cord.
Flown at the CMASS/MMMSC club launch on October 28th, 2017.

Joe Barnard of BPS has just released his Signal Avionics flight computer and it is full of cool features that any amateur rocketeer has been waiting to see!
This is no normal flight computer, Signal Alpha is a full thrust vectoring kit which essentially enables you to fly your rockets with gimbaled engines and no fins! Imagine the possibilities now open to you for experimentation in your park.
Joe does a much better job explaining all the features in the video below but for USD$299 you cannot go wrong for what this little board can do.
I look forward to it being ITAR friendly so I can get my hands on this gem!

It seems everytime I post about Barnard Propulsion Systems, Joe has gone off and succeeded in carrying out another flight! This time Scout was launched off vertical and brought back to the correct orientation.
Joe is also about to start selling the amazing little flight computer that does all this as well! Get your name on the list to be one of the first to grab it! https://www.bps.space/signal#signal-avionics
Video Caption: Running Signal’s course correction feature, Scout launched angled roughly 15 degrees from upright. Course correction held the vehicle orientation off the pad after launch, then plotted a smooth maneuver back to upright. As shown here, corrections are determined in a global reference frame, then executed in the local frame, meaning roll is not an issue(until the TVC hardware cannot keep up with the roll). Once deployed, the parachutes broke the kevlar reinforced shock cord, separating them from the body. The cord snapped at a weak point where significant heat had been experienced during assembly, which can be avoided next time with a new cord and some epoxy. The flight computer and TVC mount remained entirely unharmed by the impact.
Edit, 6/10/17: Joe flew his Scout rocket not long after posting this, new video added.
Video Caption: Ran a static fire after an overhaul of Signal’s stability software. Modifications focused on ensuring robust control loop times, which were the primary culprit of the overcorrection seen in previous Scout flights.
Joe Barnard of BPS Space has been hard at it testing his Signal Avionics package, recently flying two gimbaled rockets with the in house built system.
Head over to Patreon to help Joe out through the testing phase and soon enough you will be able to buy your own Signal Avionics package!
Joe Barnard has recently teamed up with Jonny Hyman to move one step closer to propulsively landing a model rocket. No mean feat and with a solid hobby rocket motor will not be easy.
Therefore Jonny has been carrying out a series of tests on F-15-0 motors in order to get performance data that can then be used to more accurately predict, model and achieve a propulsive landing. The video below is the 4th and final test, data from each test can also be downloaded in the video description.
